Combination smoke detector and lamp structure

Claim 2

Combination fire detector and lamp structure comprising a housing formed with a bottom wall and side walls, and open at the top thereof, said bottom wall having an opening centrally located therein, said housing including means for mounting the housing on a standard electrical outlet box, a lamp socket disposed centrally in the housing so that the socket opening may receive the base of a lamp bulb through the opening in said bottom wall, and fire detector circuitry disposed in the housing about said lamp socket, said circuitry including an audible sound producing device and a detector element responsive to the occurrence of fire at or near the detector for causing the sound producing device to produce audible sound.

Claim 3

The structure of claim 1 wherein said housing includes one or more additional openings in the walls thereof adapted to allow the passage of smoke or gas from outside the housing through the additional openings into the housing.

Claim 4

The structure of claim 1 wherein said housing includes an additional opening in the wall thereof, and wherein said detector element is disposed in the housing to protrude through said additional opening.

Claim 5

The structure of claim 1 wherein said fire detector circuitry further includes means for coupling the circuitry to an A.C. power source, rectifying means connected to said coupling means for producing a direct current from supplied A.C. power, and a rechargeable battery coupled to said rectifying means and to said audible sound producing device and detector element for receiving current from the rectifying means to charge the battery and for supplying current to the audible sound producing device and detector element when the A.C. power source fails to supply power.

Claim 6

A combination lamp adapter and fire detector comprising a housing having a bottom wall and side walls, and open at the top thereof, said bottom wall including a pair of spaced apart openings through which bolts may be inserted for screwing into the threaded bores of a standard electrical outlet box, said bottom wall further including a third opening through which electrical conductors from a lamp may be strung, the opening in the top of the housing defining a generally flat plane to enable the stable placement of the housing against a wall or ceiling with the opening in the top of the housing contiguous with the wall or ceiling, means for mounting a lamp structure on the underneath side of said housing, and fire detector circuitry disposed in the housing and positioned so as not to obstruct the insertion of electrical conductors through the third opening from outside the housing and so as not to obstruct the insertion of bolts through the pair of openings to extend from outside the bottom wall through the pair of openings and out the top of the housing, said fire detector circuitry including an audible sound producing device and a detector element for detecting the occurrence of a fire and for producing an audible sound as a result of such detection.

Claim 7

A combination lamp adapter and fire detector comprising a housing having a bottom wall and side walls, and open at the top thereof, said bottom wall including a pair of spaced apart openings through which bolts may be inserted for screwing into the threaded bores of a standard electrical outlet box, said bottom wall further including a third opening through which electrical conductors from a lamp may be strung, the opening in the top of the housing defining a generally flat plane to enable the stable placement of the housing against a wall or ceiling with the opening in the top of the housing contiguous with the wall or ceiling, means for mounting a lamp structure on the underneath side of said housing, and fire detector circuitry disposed in the housing and positioned so as not to obstruct the insertion of electrical conductors through the third opening from outside the housing and so as not to obstruct the insertion of bolts through the pair of openings to extend from outside the bottom wall through the pair of openings and out the top of the housing, said fire detector circuitry including an audible sound producing device and a detector element for detecting the occurrence of a fire and for producing an audible sound as a result of such detection.

Claim 8

The combination of claim 5 wherein said housing includes one or more openings in the side walls thereof adapted to allow the passage of smoke or other gas from outside the housing through the openings into the housing.

Claim 9

The combination of claim 5 wherein said housing includes an opening in the side walls thereof, and wherein the detector element is disposed in the housing to protrude through the opening in the side walls.

Claim 10

The combination of claim 5 wherein said fire detector circuitry further includes means for coupling the circuitry to an A.C. power source, rectifying means connected to said coupling means for producing a direct current from supplied A.C. power, and a rechargeable battery coupled to said rectifying means and to said audible sound producing device and said detector element for receiving current from the rectifying means to charge the battery and for supplying current to the audible sound producing device and detector element when the A.C. power source fails to supply power.

Claim 11

An electrical outlet box and fire detector comprising a housing having a top wall and side walls, and open at the bottom thereof, means attached to said housing for mounting the housing on a ceiling or wall stud so that the housing opening is contiguous to the corresponding ceiling or wall, a plurality of punch-out portions formed in the housing and adapted for removal by the application of pressure thereto to thereby provide openings through which electrical conduits or conductors may be inserted, a conduit extending laterally from the housing, and fire detector circuitry adapted to be powered by an A.C. source, said circuitry including an audible sound producing device disposed in the housing and a detector element mounted at the free end of said conduit for detecting the presence of smoke or other gas and for causing said sound producing device to produce audible sound, said detector element being mounted at the end of the conduit so that when the housing is mounted with the opening contiguous to a ceiling or wall, the detector element is disposed at the outside surface of the ceiling or wall.

Claim 12

An electrical outlet box and fire detector comprising a housing having a top wall and side walls, and open at the bottom thereof, means attached to said housing for mounting the housing on a ceiling or wall stud so that the housing opening is contiguous to the corresponding ceiling or wall, a plurality of punch-out portions formed in the housing and adapted for removal by the application of pressure thereto to thereby provide openings through which electrical conduits or conductors may be inserted, a conduit extending laterally from the housing, and fire detector circuitry adapted to be powered by an A.C. source, said circuitry including an audible sound producing device disposed in the housing and a detector element mounted at the free end of said conduit for detecting the presence of smoke or other gas and for causing said sound producing device to produce audible sound, said detector element being mounted at the end of the conduit so that when the housing is mounted with the opening contiguous to a ceiling or wall, the detector element is disposed at the outside surface of the ceiling or wall.
